摘要
电能表信息采集终端通信数据量较大,使得通信链路拥塞情况发生概率不断上升,为实现通信链路负载均衡以及数据传输安全,研究电能表信息采集终端通信链路拥塞安全自动控制方法。以链路瓶颈带宽、链路信息传输时延不超过限值,网络资源占有率与链路使用率方差最少构建链路拥塞自动控制目标函数,利用入侵杂草算法求解该模型,输出链路拥塞自动控制方案。在此基础上,引入条件随机场模型实现电能表信息加密式安全传输,完成链路拥塞安全自动控制。实验结果表明,所提方法应用下链路瓶颈带宽、链路信息传输时延均小于限值,网络资源占有率与链路使用率方差均有所下降,能够隐藏电能表信息原始数据特征,保证通信链路负载均衡和数据传输安全。
The large number of communicatiin data of electric energy meter information acquistion causes the rising of communication link congestion.In order to realize the load balance of communication link and the safety of data transmission,the automatic control method of communication link congestion safety of electric energy meter information collection terminal is studied.The objective function of link congestion automatic control is constructed by taking the link bottleneck bandwidth,the link information transmission delay does not exceed the limit value,and the variance of the network resource occupancy rate and the link utilization rate is the least.The model is solved by the intrusion weed algorithm,and the link congestion automatic control scheme is output.On this basis,the conditional random field model is introduced to realize the secure transmission of energy meter information,and the secure automatic control of link congestion is completed.The experimental results show that the bottleneck bandwidth and link information transmission delay of the proposed method are less than the limit value,and the variance of network resource occupancy and link utilization is reduced.The proposed method can hide the original data characteristics of the energy meter information,and ensure the load balance and data transmission safety of the communication link.
